SLICING-MACHIN E.

Specification of Letters Patent.

Application filed October 1, 1917. Serial No. 194,112.

To all 'whom it may concern.'

Be it known that we, WILLIAM H. GAR- LooK and WiLLIAM J. STUBBE,'citizens of the United States, residing at Seattle, in the county ofKing and State of Washington, have invented certain new and useful Improvements in Slicing-Machines, of which the following is aspecification. This invention relates to slicing machines; the object ofthe invention is to provide an inexpensively operated and efficientmachine whereby the slicing of bread, fish or other articles may beperformed with despatch and uniformity.

In some respects the present invention is in the nature of animprovement upon the machine disclosed in U. S. Patent No. 1,212,045,issued to us January 9, 1917, and to which reference may be had.

As compared with the prior machine, the principal features of thepresent invention consist in the novel loaf-feeding means; devices forholding the work down upon the table to accommodate any inequalities inthe thicknesses or shapes of the loaves; improved manner of assemblingand regulating the' cutting knives; and guiding means forvdirecting theslices of bread from the knives. The invention further consists inthenovel arrangement and combination of parts, as will be hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is a longitudinal section of amachine embodying the present invention. Fig. 2 is a plan view of thesame, shown partly in sec- 'tion through 2-2 of Fig. 1. Fig. 3 is afragmentary view partly in section and partly in perspective, saidsection being taken through 3-3 of '.Fig. 2. Fig. 4t is a transversevertical section, taken substantially through 4.-4 of Figs. 1 and 2.Fig. 5 is a fragmentary plan view of the complementary knife frames.Fig. 6 is a front elevational view of a portion of one of said knifeframes. Fig. .7 1s aA sectional' view through 7-7 of Fig. 6. Fig. 8 is aperspective view of a part of one of the workfeeding attachments. Fig. 9isa detail longitudinal elevational view of one of the frame members.Fig. 10 is a sectional view through d10- 10 of Fig. 9.

Supported upon a suitable framework 1 of the machine is a tablecomprising parts y2 and 21 which are longitudinally spaced toaccommodate a plate 3 therebetween. At 'each side of the frame is aslotted post l;

- movement thereof.

which serve as guides for vertically movable frames or sashes carryinggangs of serrated cutter knives 5. Each of sald sashes is formed withside rails 6 and horizontal top and -bottom rails 7 and 8, respectively.Said top and bottom rails are provided with transversely arranged slots71 and 81 to accommodate shanks 9 and 91 of knife attachments havingbifurcated heads 10 and 101 into which extend the ends of the'respective knives which are secured thereto by pins 11. The shanks 9 and91 are screw-threaded for nuts 12 and 121 whereby the heads 10 and 101are-secured in adjusted positions` laterally of the respective sashes.

Extending downwardly through the slots 72 of the upper rail 7 of eachsash (see Figs. 5 and 6 )are adjustment screws 13 engaging inscrew-threaded holes provided in the shanks 9 whereby the elevation ofthe upper heads is adjusted to regulate the tension of the knives.

The cutting edges 51 of the various knives of both sashes arearrangedVin a vertical plane indicated by :z2- 1n Figs. 1 and 5.

Said knife-carrying frames or sashes are reciprocated to movesimultaneously in opposlte directions, as by means of eccentrics 14.-141on a power-driven shaft 15, said ecthe aforesaid supporting framework 1,said chain being driven by means of sprocket wheels 22 secured to atransverse. shaft 23. The latter has mounted thereon a pulley 231 aboutwhich passes a belt 25 from a pulley 151 on the shaft 15.

Extending through the journal bearings provided in links 181 of saidchain, are transverse rods 26 to which are secured radially disposedpins orspurs 27 adapted to extend through slots 28 provided in the tablepart 2 to penetrate the bread or other article being sliced, and e'ectthe feeding The action of said spurs is regulated by means ofcontrollers provided on the ends of the rods 26, each having two studs29 \girder members 21.

and of unequal lengths, the long er and heavier ones 29 being preferablyd1sposed to have their axes in a plane with the axesby beingcarrieddownwardly with the chain `about sheaves 191 and during which theprongs are caused to slope rearwardly 4by means of curved guide plates34, one on each work as it traverses the same.

side, being engaged therespective studs As illustrated in Figs. 4 and10, the ways 31 are of insufficient depths to allow the studs 29 toenter therein. -The plate 3, as best shown in Fig. 3, is seated at itsforward and rear ends upon flange elements 35 and 36 provided on thetable parts, the forward end of said plate being sloped, as at 37, toengage a ainsta correspondingly sloped edge of ta lepart 2 while belngheld down by screws 38 at the side and rear of the ate. v

p At the frontedge, said plate is formed with comb-like teeth 39 andafford therebetween slots 391 through which operate said slicin knives,while at the rear thereof and in axlal alinement with the respectiveslots are slots 40 through which protrude disks 41` carried by an arbor42 j ournaled in bearings, not shown, provided on the underside of theplate 3.

Included in the invention are presser devices for holding down upon theplate 3 the Such pressure devices, as best shown in Figs. 1 and 4,comprise a number of rings 43 mounted upon transverse bars 44 and 441vof less diameter than the openings within said rings and supported fromtheir ends in boxes 45 and 451 movable vertically in guides provided inbranches 46 and l461 lof the e posts 4.

47 represent springs acting to yieldingly hold the boxes 45 and 451 andthe associated bars 44 and 441 in their lowermost positions.

The operation of the invention may be explained as follows j Theoperator standing in front of the machine places the articles to besliced, such as a loaf of bread indicated by L in Fig. 4, upon the frontend of the table, whereupon the conveyer prongs 27 engage in the loavesand feed the same toward and through the sashes carrying the knives 5 tobe sliced thereby, the slices thus produced being pushed ahead onto thetable part 21. Durwhich, at the higher portions of the loaves,

lng such action the conveyer prongs are successively brought intooperative engagement with the loaves at the front end of the table andare thence progressively movedthereby by the traveling prongs until thelatter are withdrawn, as before" explained.

While passing through the knife sashes,

the loaves are firmly held down on the -tablc part 2 and plate 3 bymeans of rings43 75 are resiliently held thereagainst by .means 1 ofrods 45 which are urged downwardly by .v the springs 47.

' By reason of the rings being loosely mounted upon said bars 44.-.-441,they will accommodate themselves tol any irregularities or low 'placesin the loaves, as will be understood lfrom an inspection-of Fig. 4.

When being sliced, the disks 41 extending into the interstices betweenthe slices, will serve to direct them fairly upon the delivery part 21of the table. When it is desired to change the thicknesses of slices,the plate 3 is removed and the knives 5 are shifted laterally'intodesired positions after loosening nuts 12-121 and screws 13. Being thusadjusted, another plate such as 3, in which the slots 39 and the disk 41are properly spaced, is inserted in lieu of the one removed.

In the present embodiment of our invention, the cutting edges of theknives of both sashes are arranged to be substantially in the sametransverse vertical plane and in consequence the opposite movements ofthe tWo gangs of knives will have no effect either to raise or lower thearticles being sliced, the pressure rings 43 serving to steady thearticles as they travel through the sash. 1015 The operation andadvantages of the invention will, it is thought, be understood from theforegoing.

What we claim, is-.
